Abstract: 1370743 Regulating I C engines fuel injection pumps NIPPONDENSO CO Ltd 2 Oct 1972 [2 Oct 1971] 45307/72 Heading F1B A pneumatic speed governor, for an I. C. engine having a fuel injection pump comprising a first chamber and further chamber separated by a diaphragm, the first chamber being connectible to an intake manifold of an engine and the diaphragm being connectible to the fuel pump regulating rod, so that the position of the rod depends on the pressure in the first chamber, the further chamber being connected to atmosphere by a bore for throttling expulsion of air from the chamber and by way of a check-valve in parallel with the bore and opening into the further chambers. The fuel pump 1 has a regulating rod 3 which is fixed to a rod 6 attached to a diaphragm 4 which divides a housing 2' into a vacuum chamber 2 and an atmospheric chamber 12. The vacuum chamber 2 is connected by a pipe 10 to a Venturi in the intake pipe of an I. C. engine, and the effect on the diaphragm of the vacuum produced in the chamber is opposed by a spring 5. The chamber 12 is permanently connected to atmosphere by a small-diameter bore 7 and also by a check-valve 8 which opens to admit air to the chamber. The governor prevents black smoke appearing in the vehicle exhaust when it is suddenly accelerated because the small bore 7 limits the rate at which the diaphragm can move to the left in Fig. 1 by throttling the escape of air, movement of the diaphragm and rod 3 to the left resulting in an increased quantity of fuel being delivered to the engine.

Title: Lasers
IPC: H01S5/32
Filed: 1963-11-18
Abstract: 995,715. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 18, 1963 [Nov. 30, 1962], No. 45355/63. Heading H3B. [Also in Division H1] An injection laser has an action region with a cross - sectional shape perpendicular to its smallest dimension, in the form of a regular polygon, all the side faces being optically flat. A cross - section of a rectangular parallelepipedal GaAs crystal, having electrodes at each end and a PN junction in the middle, is shown in Fig. 2. Rays following paths 21, 21a, 21b, meeting crystal surfaces 22, 24, 26 and 28 at 45 degrees are totally reflected. The crystal provides a high Q for such rays and these modes are preferentially established. Once established such modes are maintained at the expense of other modes. The crystal may be surrounded by a material having a refractive index between that of the crystal and air, to modify the internal reflection properties. Other crosssectional geometries shown are triangular and hexagonal. In the latter case (Fig. 5) three modes 46, 48, 50 are possible. Modes 48, 50 may be suppressed by using a material of sufficiently low refractive index, or mode 46 may be suppressed by notching crystal 44 at its vertices. Modes 48 and 50 are optically independent. Light may be coupled out of a crystal by means of a suitably shaped body (Fig. 4, not shown) of refractive index close to that of the crystal, placed within one wavelength of the crystal. The rays may be concentrated into a single beam. Alternatively a protuberance or groove may be provided at a crystal surface for extracting the radiation. The ratio of the refractive index of the crystal to that of the surrounding medium, for optimum mode selection, should be where N is the number of sides of the polygon formed by the cross-section.

Abstract: 1310145 Processing soybeans &c TRIPLE F Inc 2 Oct 1970 [6 April 1970] 47060/70 Heading A2Q [Also in Division A4] A method of processing an oleaginous product, e.g. soybeans, to remove heat-labile matter that inhibits protein utilization in livestock when the product is used as stock-feed consists in advancing the product along a confined path under progressively increasing pressure to generate by friction a cooking temperature, e.g. of 116 to 143‹C, and then releasing the product to atmospheric pressure whereby the oil and meal portions are momentarily separated, and part of the initial moisture content, containing a substantial amount of the heat-labile material, is released to atmosphere. The oil portions are then reabsorbed by the meal portions to form a resultant material composed of loose agglomerates which may be stored or used directly as stock-feed. Apparatus for carrying out the method comprises an auger-type extruder with an inlet 39 and outlet 84. Before reaching the inlet, beans from a feed hopper are passed through a vibratory refuse separator, including a magnet for removing any ferrous material. The extruder comprises separate flight sections 62a, 62b, 62c and 62d retained on a driven shaft 47 by a coned member 75 which coacts with an axially adjustable member 82 provided with the discharge orifice 84.
